NordLocker

NordLocker provides a private file vault that encrypts data before it leaves the user’s device and stores it in a cloud service. The vault uses a zero‑knowledge architecture, combining AES‑256, xChaCha20‑Poly1305, and Ed25519 algorithms to apply end‑to‑end encryption, ensuring that only the owner can read the contents. Files can be uploaded, synchronized, and accessed from desktop and mobile platforms, including macOS, Windows, Android, iOS, and web browsers such as Chrome, Firefox, Edge, and Safari.

The service is designed for individuals and teams who need to keep personal or professional documents confidential while still having the convenience of cloud backup and cross‑device syncing. Users can share encrypted files via email or a link that includes a unique access code, allowing controlled distribution without exposing the underlying data. The storage model also frees local disk space by offloading encrypted copies to the cloud.

NordLocker distinguishes itself by emphasizing privacy through its zero‑knowledge design, meaning the provider never sees the unencrypted files or encryption keys. The combination of strong cryptographic primitives, private sharing links, and multi‑platform availability offers a secure alternative to conventional cloud storage solutions.
